How many moles is 3.52 1024 molecules of water?
Approx. 6⋅moles of water.
How many moles are in a molecule of H2O?
The number of atoms is an exact number, the number of mole is an exact number; they do not affect the number of significant figures. The average mass of one mole of H2O is 18.02 grams. This is stated: the molar mass of water is 18.02 g/mol. Notice that the molar mass and the formula mass are numerically the same.

How many moles of water does 6.02 x10 23 molecules represent?
1 mole of any substance has 6.02 x 1023 molecules. So, in our case we have 1 mole of water.
How many moles are in 6×10 23 molecules of H2O?
Since 1 mole of particles is 6.022 x 1023, then the answer is: Number of moles = (6.022 x 1022) / (6 x 1023) = 1 x 10–1 = 0.1 moles of water molecules.
How many molecules are there in 2 moles of H2O?
One mole of H₂O contains 6.023 × 10²³ number of H₂O molecules. This is so because 1 mole of any substance contains the amount of 6.023 × 10²³ constituents in it, also known as the Avogadro number. Thus, 2 moles of H₂O will contain 2 × 6.023 × 10²³ number of H₂O molecules, that is 12.046 × 10²³ molecules of H₂O.

How many moles are in 500ml of water?
Molarity of a solution is the mumber of moles per litre. You have 0.75 moles in 500 ml.
How many molecules are in H2O of water?
One mole of water has a mass of 18 grams and a volume of 18 mL (as the density of water is 1 g per cm3). It contains Avogadro’s number of molecules (6x 10^23). Thus 1 litre of water contains 1 / 18 x 1000 x 6 x 1^23 molecules (assume you can do the maths…)
What is the mass of 6.02 x10 23 molecules of h2o?
So, one mole of water (6.022 x 10 23 molecules) has a mass of 18.02 g. One mol of NaCl (6.02 x1023 formulas) has a mass of 58.44 g.
How many water molecules are in 5.2 moles water?
Answer. Answer: There are therefore 6.02 × 1023 water molecules in a mole of water molecules.
What is the mass of 3.5 moles of water?
The mass of water is 3.5 moles*18g/mole=63g.

Which of the following correctly represents 360 g of water I 2 moles of h20 III 6.02 1023 molecules of water 41.444 1025 molecules of water?
=> The molar mass of water is 18 g/mol. 360/18=20mol. => It is also equal to 20mol×6.023×10*23molecules/mol= 1.2044×10*25 molecules. => Thus, the options (d) (ii) and (iv) correctly represents 360 g of water.
Why is a mole 6.022 x10 23?
The MOLE (mol) is a unit of measurement that is the amount of a pure substance containing the same number of chemical units (atoms, molecules etc.) as there are atoms in exactly 12 grams of carbon-12 (i.e., 6.022 X 1023).
What is 6.022 x10 23 called?
Avogadro’s number, number of units in one mole of any substance (defined as its molecular weight in grams), equal to 6.02214076 × 1023. The units may be electrons, atoms, ions, or molecules, depending on the nature of the substance and the character of the reaction (if any). See alsoAvogadro’s law.
What is 2 moles H2O?
One mole of water has a molecular mass of 18 grams. Two moles of water have a molecular mass of 18×2=36 grams. Thus the molecular mass of two moles of water is 36 grams.
How many H2O molecules are in 10 moles of water?
= 6.022×1024 individual water molecules.
How many moles are in 2.00 moles of H2O?
1 mole = 6.022×10^23 atoms. 1 water molecule = 2 Hydrogen atoms + 1 oxygen atom. So, 1 mole H2O = 1.2044×10^24 hydrogen atoms. Therefore 2 mole H2O will have 2.4088×10^24 hydrogen atoms.
How many moles are in CaCO3?
390 Unit 6 Changes in Matter The formula mass of CaCO3 is 100.09 amu and, therefore, the molar mass of one mole of CaCO3 is 100.09 grams.
How many moles are there in Cl2?
Hence, the answer is 3.33⋅1023 molecules of Cl2. Note that 6.022⋅1023 is also known as Avogadro’s number, and it can be referred to as the number of molecules in one mole of that substance. Also, I calculated 70.9 because 35.45 g/mol (the mass of one Chlorine atom) times 2 is 70.9 g/mol (Cl2 has two Chlorine atoms).
What is the molar mass of nh4 2co3?
The chemical formula of ammonium carbonate is (NH4)2CO3, a chemical compound with a molar mass of 96.09 grams per mole.
How many moles of water are there in 45g of water?
Find the number of moles in 45g of water.
Number of moles of water = Mass of water Gram molecular mass of water =45g18g=2.5.

How many moles of water are in 50 ml of water?
Answer: Avogadro’s number tells us there are 6.022 x 1023 molecules of water per mole of water. So, next we calculate how many molecules there are in a drop of water, which we determined contains 0.002775 moles: molecules in a drop of water = (6.022 x 1023 molecules/mole) x 0.002275 moles.
How many moles are in 100g of water?
There are approximately 5.55 moles of water in a 100-gram sample of water.
